When selecting a special milling cutter for woodworking engraving machine, it is necessary to rely on the following points.
First, the tool rotation direction and feed direction
The tilting direction of the cutting edge on the tool is determined according to the direction of rotation of the machine tool shaft and the direction in which the wood workpiece is fed.
Second, the cutting direction
In solid wood cutting, the wood cutting is divided into longitudinal, transverse, end and longitudinal, longitudinal and transverse directions according to the direction of the blade relative to the wood fiber.
Third, the tool and workpiece stability
The stability of the tool and the workpiece during the cutting process includes several aspects. The stability of the workpiece means that the wood workpiece is smoothly fed during the cutting process without jumping. Measures taken to enhance the stability of the workpiece mainly reduce the center of gravity of the workpiece and increase the contact area.
Fourth, the nature of the material being cut
Wood cutting objects are solid wood and wood composites. Solid wood can be divided into soft materials, hard materials and modified wood; wooden composite materials include plywood, veneer lumber, particle board, oriented strand board, large particle board, gypsum particle board, cement particle board, hard fiber board, medium density Fiberboard, high-density fiberboard, blockboard, rubber composites, etc. Some wood or wood composite parts are also treated with one-sided or double-sided veneers.
